I'm not going to lie, this prologue is very interesting, one of the most weird and strange expiriences I have ever played.
Even more strange comparing it to the earthbound series in it's own style. The atmosphere of being repressed and hated upon, while being this robot with real struggles. Having your nice and corforting friends, that unfortunately die as the end.
I never really felt this estrangement in any games at all, really good job. This feeling fits really well with the theme you were going for.
The artwork is also really unique, like you actually put your very soul into it. The design of the robot characters is very nice and neat.
The chemistry of main charater is interesting and great, my favourite is how the doctor calls their creations "babies".
In my own perspective this are prologue's main strenght.
As for other aspects of the game, they are somewhat lacking, the example being in the first actual battle. It was hard without looking at what emotions do in the menu. Still, a good game in my opinion. I cannot wait to see what the updated version looks like, and the rest of the planned game. I wish you fun making the game of your life.
